A method is described for the calculation of differential rate constants using an empirical description of the time dependence of the product of integral rate constant and time or of conversion. The method has been verified for quaternization reactions of poly(2-dimethylaminoethyl methacrylate), poly(4-dimethylaminomethylstyrene), poly[N-(3-dimethylaminopropyl)acrylamide], poly(4-vinylpyridine), poly(iminoethylene), and [4-bis(2-hydroxyethyl)aminomethylstyrene] as a function of conversion of the reaction. The calculations were carried out using reported data on the dependence of conversion on time.
